It is B. if i'm not mistaking
Answer:
6 m/s
Explanation:
Well we can find acceleration a=v/t = (21-0)/7=3 m/s^2
vf=at+v0, use this equation to solve for the vf
vf=3(2)+0=6 m/s was its speed at 2s
Answer:
convection, conduction, and radiation
Explanation:
Answer:
t=0.0625s
Explanation:
F=number of swings/time taken
DATA
Frequency=4.0Hz
number of swings from Q to R
=1/4
time taken=?
Frequency=number of swings/time taken
make t the subject of the formula
t=n/f
substitute the given date
t=0.25/4.0
t=0.0625s
option A is collect
